onmouseover [=String] The string is the function name to be called when the mouse
pointer has moved over the sprite. This CAN include arguments so
mySprite.onmouseover="dosomething(x,y,z)" would pass the variables x,y,z
to the function dosomething
onmouseout [=String} The string is the function name to be called
onclickdown [=String] The string is the function name to be called
onclickup [=String] The string is the function name to be called

IMPORTANT: To use any of the last four properties you need to create an object of the Class Mouse

Our exercice will be very easy. We will use "mouse=over" and "mouse-out" to change the face of a card.

Educational games using pairs of cards are very usual.

To have a so big card over the floor of a Lot is not very real but nothing at the OLPCities is very real :-)
